"In a move that has raised eyebrows, Microsoft has submitted a patch to the WebKit project to extend the open source rendering engine with a prototype implementation of the Pointer Events specification that the company is also working on together with Google, Mozilla, and Opera. WebKit is the rendering engine used in Apple's Safari and Google's Chrome browsers, making Microsoft's work a contribution to products that are in direct competition to its own."

When I see news like this, I always wonder, what are Microsoft's intentions?

In this case, though, the guy who posted the patch, Scott Blomquist, happens to be a friend of mine. Puts a completely different perspective on things: it's no longer a big corporation - just a developer who wants to help out.
